IPC: E21B11/00
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To discharge soil and sand to a soil-sand receiver, and to move soil and sand to a separate place by hanging up a bucket, on which soil and sand are loaded, and inverting the bucket under the state in which an arm is rotated and a pin for the bucket is received to a pin receiver. SOLUTION: A bucket 18 for discharging soil and sand has a pair of pins 22 projected to places eccentric from the place of the center of gravity on the outside of the lower end section of a cylindrical bucket main body section 20. The bucket shifter 10 has a crane body 30 and a winch 32, and the bucket 18 can be moved vertically and horizontally. When the bucket 18 is placed in specified height and an arm 34 is rotated vertically, pin receivers 40 receiving the pins 22 are installed to the arm 34. When the bucket 18 is hung down and soil and sand are charged, the bucket 18 is lifted up to specified height. The arm 34 is turned in the vertical direction, and the pins 22 are received into the pin receivers 40. The arm 34 is revolved, and the bucket 18 is rotated around the pins 22 by its own weight of the bucket 18.  Soil and sand are discharged to a soil-sand receiver 66, and discharged at a place separated from a pit.

Title: Testing method
Inventor: IKEZAWA MASUSHI
IPC: H01L21/822
Filed: 1983-04-12
Abstract: PURPOSE:To reduce the number of test patterns at a digital signal processor by a method wherein an operation controlling clock is inverted according to a test signal, operation output is latched by the clock thereof, and a gate is opened according to inverted output. CONSTITUTION:A program counter PC operates synchronizing with a clock CLK1 at working time, and a command is read from a read-only memory ROM to be decorded by a decoder DEC when the counted value of the counter becomes to (b). At testing time, a signal TST is set to TST=1. Accordingly, a clock CLK2 generating in the same phase with the clock CLK1 is outputted from a gate AN3, and when the decoder DEC is outputting a latch signal (a), a circuit ACC is latched according to the fall of the clock CLK2. A gate G is opened at this time according to output of a gate AN1, and output can be obtained as it is at an outside bus-bar ODB. Setting to registers R1, R2, and operation at an arithmetical unit ALU are performed as usual. When an operational command is put into practical effect according to this construction, a result is outputted automatically by the same PC address, and construction of test patterns can be attained easily.

Title: Windshield wiper driving controller
Inventor: KITAYAMA MASAKI
IPC: B60S1/08
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To dispense with an inflow checking diode for a reverse connecting current due to a counter electromotive force to be generated at the time of being set up in a high mode, in this windshield wiper driving controller. SOLUTION: A combination switch 9 sets up an operating mode of a wiper motor 1, and at the time of setting up an intermittent mode, two power elements 10 and 11 are turned on or off by an integrated circuit 8, thereby intermittently driving the motor 1. A connecting terminal 14 of the power element 11 is connected to an Lo terminal, 6 via a switch means 13 added to the combination switch 9. When this combination switch 9 is set up in a Hi mode, counter electromotive force is produced in the Lo terminal 6, but since the connecting terminal 14 of the power element 11 is insulated from the Lo terminal 6 by the switch means 13, such a possibility that the reverse connecting current might flow into the power element 11 is prevented from occurring.

Title: Measuring method for fine displacement and fine tilt angle
Inventor: YANABE SHIGEO
IPC: G01C3/00
Filed: 1988-03-18
Abstract: PURPOSE:To accurately measure the fine displacement and tilt angle of a reflecting surface by photodetecting reflected light beams from a body to be measured by an optical position detecting means, detecting the shift in the position of its light spot image, and providing a lens in the optical path of the reflected light beams in a free entering and exiting state. CONSTITUTION:A laser light 3 is projected on the reflecting surface 1 of the body to be measured such as a slider and photodetected by the optical position detecting means 6 on the optical path of the reflected light at a distance l, and the lens 7 whose focal length (f) [f<a and 1/f=1/a+1/(l-a)] is arranged in the optical path of the reflected light beams at a distance (a) so that the lens enters into and exits from the optical path freely. When the fine displacement (h) is measured by this constitution, the lens 7 is inserted and the displacement (h) is detected by a specific arithmetic expression from the movement quantity of the light spot image of the real image p' of the irradiation point (p). Further, when the fine tilt angle theta is measured, the lens 7 is put off the optical path, the distance delta1 between real images p' and p1' is found, and the theta is calculated from delta1=2thetal. Consequently, the displacement and tilt angle of the slider, etc., are measured with extremely high accuracy without being affected by the material, shape, etc., of the body to be measured.
